Specific objects of my invei'iion are to provide it pair of sleeves that. roatory upon n eonnnon mais having their inner oppositely disposed ende provided with toohed c geen ing o1 gears. which gears are 'meshed with en inferv posed plenetary pinion Hint is carried by :i

hub, the saune being rotiitoriljgf mountednbout the sleeves; to provide o conpii'ng' melnberzind connections iherefor 'adjacent to the outer end of one of ,the sieeves whereby; the said. sleesv` is locked in eon'oectionwith the hub member or "freed therefrom und looked agninst rotation upon its; wie; io provide a simple :ind economical construction whereby the parte are ready i. to provide n. 'friction ehrlich in connection with the drive nieniber,jit being unders'wod that the drive member may constiu'te eilher the hnh or that: Egsleeve which is free to' revolve upon its liz-iis ail all times. and to provide n manually operated :iiieliy disposed plunger in connect-ion with the coupling menne wherel'ij/ the position of the saine is shifted to effect changes in the speed oil the driven sleeve member or to discografie smid drivel'i Sleeve -nienilier entirely from thc drive member.
